Abstract: A system includes a detection module, a control module, an input module, and a determination module. The detection module is configured to obtain information from one or more detectors corresponding to a condition of a transportation network. The control module is configured to issue control messages using the information obtained. The input module is configured to receive a request for the control module to enter a test mode corresponding to an alteration of at least one of an input or an output of the control module from an operational mode. The determination module is configured to determine if an authorization condition corresponding to a physical state of one or more functional activity module of the transportation network is satisfied. The control module is transferred to the test mode if the authorization condition is satisfied and maintained in the operational mode if the authorization condition is not satisfied.
